The Casio Rangeman GPR-B1000 is a big watch for big adventures

The Casio Rangeman GPR-B1000 is comically large. That’s the first thing you notice about it. Based on the G-Shock design, this massive watch is 20.2mm thick and about 60mm in diameter, a true dinner plate of a watch. Inside the heavy case is a dense collection of features that will make your next outdoor adventure great.

GPR-B1000, which I took for an extended trip through Utah and Nevada, is an outdoor marvel. It has all of the standard hiking watch features including compass, barometer, altimeter, and solar charging, but the watch also has built-in GPS mapping, logging, and backtracking. This means you can set a destination and the watch will lead you and you can later use your GPS data to recreate your trek or even backtrack out of a sticky situation.

This is not a sports watch. It won’t track your runs or remind you to go to your yoga class. Instead it’s aimed at the backwoods hiker or off piste skier who wants to get from Point A to Point B without getting lost. The watch connects to a specialized app that lets you set the destinations, map your routes, and even change timezones when the phone wakes up after a flight. These odd features make this a traveler’s dream.

The watch design is also unique for Casio. Instead of a replaceable battery the device charges via sunlight or with an included wireless charger. It has a ceramic caseback – a first for Casio – and the charger fits on like a plastic parasite. It charges via micro USB.

It has a crown on the side that controls scrolling through various on-screen menus and the rest of the functions are accessed easily from dedicated buttons around the bezel. The watch is mud- and water-proof to 200 meters and it can survive in minus 20 degrees Celsius temperatures. It is also shock resistant.

The $800 GPR-B1000 is a beefy watch. It’s not for the faint of wrist and definitely requires a bit of dedication to wear. I loved it while hiking up and down canyons and mountains and it was an excellent travel companion. One of the coolest features is quite simply being able to trust that the timezone is correct as soon as you land in Europe from New York.

That said you should remember that this watch is for “Adventure Survival” as Casio puts it. It’s not a running watch and it’s not a fashion piece. At $800 it’s one of Casio’s most expensive G-Shocks and it’s also the most complex. If you’re an avid hiker, however, the endless battery, GPS, and trekking features make it a truly valuable asset.
